SPECIFICATION forming part of Letters Patent No. 769,136, dated August30, 1904.

Application-filed October 17, 1903.

To LZZ whom 712? muy concern:

Be itknown that I, ADELBERT A. HENDER- soN, a citizen of the UnitedStates of America, residing at Wilkinsburg, in the county of Alleghenyand State of Pennsylvania, have invent-l ed certain new and usefuly'Improvements in Letter-Sheets and Envelope, of which the fol'- lowingis a specification, reference being had This invention relatesvtocertain new and ing-envelops, and the primary object of the invention isto provide means whereby frequent mistakes caused by the placing'of alet-` ter-sheet in the wrong envelop or the errone-v ous addressing ofthe envelop maybe absolutely avoided. f

Another of the main objects of the invention is to provide aletter-sheet and envelop therefor in which the address 'which appears onthe outer face of the envelop may be made direct on the letter-sheet atthe time of writing the letter on the latter and which address issecurely affixed to the envelop by the sealing of the letter after theletter-sheet has been placed therein.

Briefly described, the invention comprises an envelopmade from asuitable blank and entrance to the pocket of which may be had eitherfrom the end of the envelop or from the side edge thereof, as may bedesired.. This envelop is provided with two sealing-naps that areadapted to engage a portion ofthe lettersheet which carries the addressand securely affix the said portion to the envelop. The let-l ter-sheethas an extension or tab on its one end, and where the letter istype-written vthis 'eX-. tension or tab is` adapted to be foldeddownonto the letter-sheet prior to inserting the letter-sheet into thetype-writer, and the address (including the street and number) is thentype-writtenon this extension or tab. After the letter-sheetis taken outof the type-writer, the extension or'tab is turned back, whereby thelette'r-sheet-may be folded without inclosing the extension or tab inthe folds, and the folded letter-sheet is then inserted into the SerialNo. 177,471. (No model.)

envelop with the extension or tab projecting outside the envelop. Theextension or tab is then folded down on the envelop and thesealing-iiaps of the latter are engaged with said extension or tab so asto firmly aiX the same to the envelop. The address which has beentype-written on the extension or tab being on the reverse side to thaton which the letter is written, it will be evident that the said addresson the tab or extension will appear on the outer face of the envelopwhen the eXtension or tab is folded thereagainst.

In describing the invention in detail ref- .erence is had to theaccompanying drawings, l forming a part of this specification, andwherein like numerals of reference indicate like parts throughout theseveral views, in which- Figure l is a plan viewvof the preferred formof letter-sheet. Fig. 2 is a plan view showing the tab folded down onthe sheet with the ad- 'part of the same, showing they extension or tabfolded thereon. Fig. 11 is a partly-folded view of a modified form ofenvelop. Fig. l2 is a planview of a part of the envelop involved in theform shown in Fig. ll. Fig. 13 is a plan view of another part of saidenvelop. Fig. 14 is a plan view of this'form 0f envelop, showing thesame sealed with the letter there- 'in and the extension or tab affixedto the envelop.

` The letter-sheet l isof the form shown in Fig. 1, is substantiallysquare or rectangular in form, and.A is provided atthe one end with anextension or tab 2.

' is adapted to have the address (including street,

This extension or tab Fig. e is a. View of the,

number, and city) written thereon on the reverse side tothe face onwhich the letter is written. When the letter is written by thetype-writer, it will be evident that this eXtension is folded down onthe letter-sheet after inserting the latter in the machine. It is alsoevident that where a carbon system is used the address made on theextension or tab as well as the address at the beginning of the lettermay be made on the carbon copy, and where a copying system is used bothaddresses may be made to appear in the copying-book by simply leavingthe tab or extension folded down against the letter-sheet when placingthe letter in the book for copying. I may form the letter-sheet 1 withan extension or tab 2 at one corner thereof, as shown in Fig. 9, inwhich construction the letter-sheet will be folded on crease-lines 3 4and the tab on erease-line 5. In the construction shown in Figs. 1 and 2the letter-sheet is folded on.

crease-lines 6 7 and the extension or tab on crease-line 8.

The envelops as employed to receive the letter-sheet may be of the formas shown in Figs. 4 to 8, inclusive, which embody a blank consisting ofa front 9, side wings 10, back 11, and a sealing-flap 12. The back 11 isprovided along its two side edges with a gummed surface 14 and on thesame side adjacent its free end with a gummed surface 15, this gummedsurface 15 of the back forming an auxiliary sealing-hap, as will behereinafter described. In folding the blank above described into envelopform the side wings 10 are folded over and aiiixed one to the other bythe adhesive surface 16, provided on one of the wings. The back 11 isthen folded over onto the side wings, the gummed or adhesive surfaces 14being sealed to the side wings 10 and to the extension 17 of said wings.Auxiliary sealing-iiap 15 is at this time left unsealed. When theletter-sheet has been folded as seen in Fig. 8, it is inserted in theenvelop, Fig. 6, the extension or tab 2 being left outside the envelop,and this extension or tab is then folded down onto the back of thefolded side wings 10 10. The end of the extension or tab is then engagedunder the auxiliary sealing-Hap 15 and the latter sealed down onto theextension or tab. The sealing-Hap 12 is then also sealed down onto saidextension or tab, securely aflixing the same to the envelop, as seen inFig. 7.

In Figs. 11, 12, 18, and 14 is seen a modified form of construction ofenvelop in which the letter'` is placed therein from the side edge ofthe envelop. This envelop comprises a blank embodying a front 18, a back19, a flap 20, integral with the front 18, and end flaps 21, alsointegral with the front 18,'and a sealingiiap 22. To formv the envelopfrom this blank,

back 19 is placed on the rear face of front 18, the end wings 21 foldedover and secured to back 19, at the ends thereof. The ilap 20 is thenfolded over onto back 19 and the gummed portions 23 secured thereto, thegummed portion 24, however, being` left unsealed. The envelop is thenready to receive the letter, and the latter is placed therein with theextension or tab 2 or 2, as the case may be, outside the envelop and thefree end of the said extension or tab engaged underneath auxiliarysealingflap 24, which latter is sealed down on said extension or tab.The main sealing-flap 22 is then also sealed to said extension or tab,securely aixing the same to the envelop, as seen in Fig. 14. By thismeans it will be observed that an error, such as the placing of a letteraddressed to one person in an envelop addressed to another, isabsolutely impossible, as no addressing of the envelop ym .wf is done,the address being placed on the letter, and when the latter is placed inits envelop and the extension or tab aiiixed to the envelop the latteris addressed ready for mailing. lt will also be observed that theaddressing of the extension or tab with the full address of theparty-that is, street, number, &c.-enables the dispensing with the fulladdress at the beginning of the letter, yet assures a perfect addressingof the envelop and also gives a record of the manner in which theenvelop was addressed, as either the carbon copy or the book-copy of theletter will show the eo1nplete address which was written on theextension or tab. It will also be observed that no addressing of theenvelop per .we being required, the work of sending out the inail willbe materially facilitated.

It will be obvious that various slight changes may be made in thedetails of construction without departing from the general spirit of myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is"

1. A letter-sheet having an extension or tab on one end adapted toreceive the address for the envelopgthereon on the reverse side to theface of the letter-sheet on which the letter appears, substantially asdescribed.

2. A letter-sheet having an extension or tab adapted to receive theaddress for the. envelop thereon on the reverse side to the face of theletter sheet which receives the letter, and adapted to be folded on andaiiixed to the ou ter face of an envelop.

3. A letter-sheet having an extension or tab on one end, adapted toreceive the address for the envelop and to be folded against thc outerface of an envelop.

4. A letter-sheet having an extension or tali adapted to receive theaddress for the envelop,
